Hydrocephalus is one of the common birth defects that affect the brain development; it affects 2 of every 1000 births in the US (NIH, 2005). The term hydrocephalus comes from the Greek words; hydro means water and cephalus means head, as the name implies, the primary characteristic of this disorder is the excessive accumulation of CSF or cerebrospinal fluid in the brain (Piatt,2011), the cerebrospinal fluid is the colorless fluid that bathes the brain and the spinal cord, the excessive accumulation of this fluid can lead to an abnormal widening of the ventricles of the brain, and this widening can cause pressure on tissues of the brain (NIH, 2005). The ventricular system of the brain consists of four ventricles and narrow passages between …show more content…

communicating hydrocephalus occurs when the flow of the CSF in blocked after it passes and exits between the ventricles, in this type the CSF can still pass between the ventricles and that is why it is called communicating hydrocephalus. The non-communicating hydrocephalus is also called "obstructive" hydrocephalus, it occurs when the flow of the CSF is blocked in one or more of the narrow passages between the ventricles (NIH, 2005), one of the most common causes of hydrocephalus is the narrowing of a small passage connecting the third and fourth ventricles in the middle of the brain, the passage is called aqueduct of Sylvius and the narrowing of it is called aqueductal stenosis. In addition to these types, there are two forms that do not exactly fit in the categories and they mostly affect adults: hydrocephalus ex-vacuo and Normal Pressure Hydrocephalus (NPH) (Piatt, …show more content…

In infants, the sutures that connect the bones of skull are still open, that is why their skulls can expand to accommodate the buildup of CSF. The symptoms of hydrocephalus in a baby may include a rapid increase in head circumference and abnormally shaped head, bulging at the soft spots, swollen veins, vomiting and downward cast of the eyes. Adults and older children may experience symptoms that differ from the ones mentioned above because of their skulls; symptoms may include nausea, sleepiness, double or blurred vision, difficulties with motor skills and balance, mental impairment and seizures (NIH, 2005). Some types of hydrocephalus are misdiagnosed and not properly treated; Doctors may use different tests including brain scans such as computed tomography, neuropsychological tests, magnetic resonance imaging, a spinal tap or lumbar catheter, in order to help them accurately diagnose hydrocephalus. A doctor selects the appropriate diagnostic tool based on the age of the patient, the overall health and the presence of other known abnormalities (Piatt, 2011). The most standard thing to do in order to treat hydrocephalus is to surgically insert a shunt system. The shunt system changes the course of the flow of the CSF to a different area in the body, where it can be absorbed normally into the circulatory

In the chapter “Epiphenominalism and Eliminativism", from Objects and Persons, Trenton Merricks present an argument against the existence of baseballs. His argument revolves around a scenario of a baseball hitting the window and causing it to shatter. According to him, the baseball did not cause the window to shatter, its atoms did, because they have the causal powers and the baseball does not (Merricks, p. 61). Merricks uses the Alexander's dictum “to be real is to have causal powers” (p. 65), to make his argument that since the baseball itself has no causal powers, there is no good reason to believe it exists (p. 73). In his paper, Merricks first explains the causal principle; then, he defends each premiss of his argument by responding to

One of the leading guesses is that Transverse Sinus Stenosis is the cause of Pseudotumor Cerebri. Transverse sinus stenosis is the narrowing of a vein in the brain. A Transverse Sinus Stent is a stent holding open/widening this narrow vein. It was found that most pseudotumor cerebri patients had Transverse Sinus Stenosis as the cause of these conditions. In a clinical trial this

Monti Jones is a 2-year and 7-month-old male. He was born on 8/31/2012 at 26 weeks gestation weighting 1Ibs. leaving him hospitalized for 3 ½ months due to his premature delivery. Monti's premature birth history significantly impacted his early development where he endured chronic lung disease, was incubated 1-½ months due to a bleed in the cerebellum, received oxygen at home for one month, and experienced developmental delays. After sustaining a traumatic brain injury (TBI) in 2014 from a fall Monti was hospitalized and received rehabilitation for 4 ½ months.

Ocpti are quite gentle creatures. These cephalopods are quick, cunning and very adventurous. Unless they are in venery, they do not use their hypobranchial gland (ink sack), and rarely has there been cases of cephalopod attacks (http://www.thecephalopodpage.org/bluering2.php ). The only octopus that is often found and bitten people is the Blue Ringed Octopus. The Blue ringed octopus is deadly, and its venom can kill 26 adults in just a few minutes.

But cerebral spinal fluid is just the doctors' fancy way of saying brain grease. And brain grease works inside the lobes like car grease works inside an engine. It keeps things running smooth and fast. But weirdo me, I was born with too much grease inside my skull, and it got all thick and muddy and disgusting, and it only mucked up the works. My thinking and breathing and living engine slowed down and flooded.

People cannot diagnose CTE until an autopsy has taken place, and they diagnose it with Tau protein. CTE is believed to have four stages that affect the human body. These stages are dangerous because many victims think it’s normal aging, and then they catch it too late (“What is CTE”). The first stage might not come until months to years after the head trauma. This stage includes bad headaches and

Your child’s health care provider may suspect Sotos syndrome from your child’s head size and facial appearance. The health care provider will also do a physical exam. Your child may have tests to rule out other developmental conditions and confirm the diagnosis of Sotos syndrome. These tests include: • X-rays to check for increased bone growth for your child's age. • A blood test to look for the NSD1 gene.

Evaluation of persons for surgery is generally recommended only after focal seizures persist despite the person having tried at least two appropriately chosen and well-tolerated medications, or if there is an identifiable brain lesion (a dysfunctional part of the brain) believed to cause the seizures. When someone is considered to be a good candidate for surgery experts generally agree that it should be performed as early as possible. Surgical evaluation takes into account the seizure type, the brain region involved, and the importance of the area of the brain where seizures originate (called the focus) for everyday behavior. Prior to surgery, individuals with epilepsy are monitored intensively in order to pinpoint the exact location in the brain where seizures begin. Implanted electrodes may be used to record activity from the surface of the brain, which yields more detailed information than an external scalp EEG.

A concussion is a serious brain injury from a physically traumatic event. It is caused by either a physical blow to the head or being forcefully shaken. Either of these situations cause the brain to hit the inside of the skull. The most common symptom of a concussion is a very bad headache. But a person will also feel confused and dizzy.

Epilepsy is a group of related neurological disorders characterized by a tendency of recurrent epileptic seizures and fits. Epilepsy is the fourth most common neurological problem whose prevalence affects 5-8.4 out of every 1000 people (depending on prevalence studies used). Epilepsy is expensive for both hospitals and patients and results in an overwhelming $15.5 billion in medical costs and lost or reduced earnings and production. Epilepsy is a neurological disorder that more likely originates in the hippocampus, temporal lobes, or motor cortex due to these areas being particularly sensitive to certain situations that can provoke abnormal electrical transmissions. Although sometimes misdiagnosed, several tests are conducted to correctly diagnose
